To all whom it may concern:

Be it known that I, HENRY J. SCHNEIDER, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Scraping Devices, of which the following is a specification.

The present invention relates to a machine for scraping lugs on lead battery plates, and an object of the invention is to provide means by which a battery plate lug may be effectively scraped without producing any curling of or injury to the lug.

To this and other ends the invention consists of certain parts and combinations of parts, all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings Figure 1 is a plan view of a machine constructed in accordance with the present invention;

Fig. 2 is a side elevation of the machine;

Fig. 3 is an enlarged sectional view of the machine adjacent the scraping devices;

Fig. 4 is a detail view of the scraping head, showing the supporting mounting therefor;

Fig. 5 is a view similar to Fig. 6, showing the scraping devices operating on the lug; and

Fig. 6 is a sectional view on the line a-a, Fig. 3.

Battery plates made from lead are usually provided with lugs through which electrical connections are established with the plate. These lugs are required to be scraped in order to remove the oxidized surface which interferes with the electrical connection. Generally, this scraping has been accomplished by hand which is not only slow work but tends to injure the lugs. According to this invention, a means is provided which operates on a number of faces of the lug, preferably all four faces simultaneously in the direction of the length of the lug to clean the lug without producing any injury thereto or any curling thereof.

Referring more particularly to the drawings wherein is illustrated one embodiment of the invention, 1 indicates a support in the form of a table having a guide 2 thereon against which one edge of the plate 3 is brought while such plate is resting upon the table 1. At the same time that the plate is brought against the guide 2 its lug 4 is projected beyond one side of the table for operation upon by the scraping devices.

The scraping devices in this instance comprise four scraping blades 5. 6. 7. and 8. The blades 5 and 6 cooperate with the wide sides of the lug 4, while the blades 7 and 8 cooperate with the narrow or edge sides of the lug 4. The blades 5 and 6 have their cutting edges arranged at opposite angles to each other, while the blades 7 and 8 are preferably at right angles to the longitudinal I axis of the lug 4. By having the blades 5 and 6 at angles to each other, all tendency to produce curling of the lug 4, which would occur if the blades were parallel, is overcome. In operation, the blades 5 to 8, inclusive, are moved without engaging the lug 4 toward the base or inner end of the lug, after which all blades are brought into engagement with the lug 4, and are then moved in the direction of the'longitudinal axis of the lug, being simultaneously drawn over the four faces of the lug toward the free end of the latter, thus cleaning such faces.

In the illustrated embodiment, all of the blades are supported on the reciprocating frame 9 guided at 10 on the bed 11 which, in this instance, is integral with the supporting table 1 and extends laterally from the latter. On this frame is a projection 12 formed with four recesses in which the inner ends of four arms 13, 14, 15 and 16 are secured, said arms being made of spring material and extending in one and 'the same direction from the projection 13, their outer ends being provided, respectively, with scraping knives or blade clamps 17, 18, 19 and 20 for the respective knives or blades 5, 6, 7 and 8. Each knife may be held in its clamping head by a tapered pin 21 which has one face bearing against the knife and the other against the head, a nut 22 on the end of the tapered pin serving to hold the latter firmly against the knife to bind the knife in the clamping head.

Normally the knives are held away from the lugs by the spring in the arm, said arms being guided in the ring frame 23 which is secured by bolts 24 to the sliding frame or carriage 9. In order that they may be moved so as to engage the plate lug after the knives have been carried toward the base or inner end of the lug, a mechanism is provided which comprises, in this instance, an

is preferably provided with a plurality of:

cam surfaces 27 cooperating with a cam surface28 on one of the clamps, said ring also having portions 29 concentric withthe ring which will permit a movement of the ring without producingany movement in the H H whlch-surrounds an-ecceritnc-BT on the-shaft arms 13 to 16,- inclusive. It is apparent that, when the ringv 24 is turned to cause the cam portions 27 to engage the portions 28, the arms, 13 to 16, inclusive, will be moved toward each other to cause the knife blades to engage the plate lug and, when the ring 2 1 is turnedin the opposite direction, to cause the cam portions 27 to ride off the cam portions 28 on to the concentric portions 29, the arms 13: to 16, inclusive, will separate the knife blades.

Movement of the operating ring 2 1 may be effected in any suitable manner. In this instance, a spring 30 is anchored on the carriage 9 and projects forwardly into sliding engagement with the" lug 31 on the under side of the ring 245 This spring 30 normally tends to hold thering 24 in a central position. The projection 31 isalsoprovided with the operating projection 32, the opposite faces of which,"as shown in dotted lines inFig;'3,-arebeveled. This operating projection is, in turn, adapted to travel in a trackway formed by an elongated projection 33, whose opposite ends are beveled, as shown in' Fig-3 111 dotted lines. WVhen the carriage 9 is moved so as to bring the knives at the inner end of the battery lug, the projection 32 will lie in advance of the projection 33, as'shown in dotted lines in Fig. 3. On the rearward movement of the carriage 9 the beveled face of the projection 32, ad'- jacent' the forward beveled face of the projection 33, will cooperate with such beveled face of the projection 33, and cause a turning movement of the ring 2 1 sufficient to bring the'knives into engagement with the plate lug. After this engagement is once established, and during the continued movement of the knives toward the free end of the battery lug, the projection 32 will '00- operate with one sideface of the projection 33 and hold the knives in this scraping position until the end of the battery lug is reached, after which the spring 30 will shift the ring 24c so that the forward face of the lug 32 will be brought opposite the rear face of the lug 33, thus causing the knives to move away from each other, and, upon the forward movement of the knives, the forward face of the lug 32 will cooperaterwith the rear face of the lug 33 and shift the ring 24, so that theconcentric portions 29 will cooperate with the cam'porti'ons 28, thus produeing no movement in the-knifeisupporting arms 13 to 16, inclusive, until after the forward end of the lug 33 is reached, when the spring 30'will again act and shift the lug 32 in advance of the lug 33 so that the s'c'rapingaction will again take place on the return movement of the carriage 9. I

Movement of the carriage 9 be effected inany suitable manner. In this instance, a pitman 3-1 is pivotally connected at 35 to the carriage 9',*and has a' ring 36 38-. to which a wormwheel 39 is secured,

,This worm' wheel 39 is journaled on the with the clutch member 42 in order that mo-, tion may be transmitted to the, shaft 41 and through the latter to the carriage 9.

Control of the connection between theme,- tor 416 and the scraping devices maybeeffected' by the battery plate ,3, and to this end a two-arm lever 47 is pivoted at 458011 the table 1 withroneof-its two arms prolvide'd with a projeictionslt) lying in the path of the topedgeof'the battery p1ate,,so that when the battery plate is moved onthe table 1, to be positionedin the path-of the scrap ing devices, such plate will engage thelug 49 and-shift the lever 17; on" its pivot 48. As the lever shifts onits pivot; it produces a: pulling action in the rod 50 which is pivotedat 51 to, the opposite end" of the lever 47, and is also pivoted at 52 to a lever 53' which, in turn, is pivotedxat' 54 to the baseframe 11 and has a yoke 55; atiits free end engags ing within a grooved collar 56 on'the' clutch' member 13. The pull on the rod 50' shifts the clutch member 43 into engagement with the clutch member 42 and causes the scraping devices to operate. The operator of the machine should, after the scraping devices havepassed beyond the end 'ofthe battery lug 4, remove the battery plate,=andthis action permits" the spring e l-"to separate' the clutch members 12' and 13,thus stopping the scraping devices and at the .same time causing the proj e'ction49 to be shifted,-sojthat when another battery plate3. is introduced on the table 1 and-'has'itslug-' projected into the path of the scraping devices, the latter will again be operated to scrape'such'lugk 7 From the foregoing it} will be seen that there has been provided a Scraping means which effectively scrape-s a plurality of faces 1 30 so that it may be brought intoengagement of a lu of a lead plate without injury to the lug and without producing any curling action in the lug. The scraping devices may be adjusted readily to lugs of different sizes and they are controlled through the battery plate, the introduction of the battery plate in a certain position on the machine automatically starting the scraping devices into action, which action automatically stops when the operator removes the battery plate from the machine.
